Abstract:

Today, most traditional method used in the research of immune cells, such as flow cytometry and microscopy, are based on average values of cell responses. However, immune cells are heterogeneous and respond differently to a given stimuli. There is also a risk that important, but rare, behaviors of individual cells are missed when a larger population of immune cells is analyzed. Also, flow cytometry and microscopy do not allow long-term survival of cells; these methods lack the ability to do dynamic long-term analysis of motile immune cells, i.e. studies of cell-cell interaction

Abstract:

The human society has throughout history been faced with great challenges. These challenges however hold the opportunity for us humans to learn and grow as a species in whole. As the human population is increasing, more attention has been focused to the medical eld to deal with the challenge of curing and treating people in larger scales at a faster rate. A particular challenge today is to meet the high demand in organ transplants. The number of human donors is scarce relative to the demand, and the transplantation is never guaranteed to be successful. Therefore allot of research is being cond

The 1980's heralded the discovery and identification of extra-pituitary sources of the neurohypophysial hormone oxytocin in non-neural tissues of several animal species. The presence, location and biosynthesis of significant amounts of oxytocin in the ovarian corpus luteum was followed by the immunocytochemical demonstration of an oxytocin-like peptide in the testicular interstitial cells. Leydig cells, which comprise up to 80% of the testicular intertubular cell population, are known to synthesize testosterone in situ. Indirect evidence indicated that an oxytocin-like peptide was also present

Abstract:

During tumorigenesis many oncogenic pathways are reprogrammed and modulate mitochondrial metabolism, decreasing oxidative phosphorylation (OXPHOS) activity. They inhibit ATP synthesis and ROS production from OXPHOS complexes favoring metabolic switching toward a more glycolytic metabolism and tumor growth. This metabolic rewiring is well established in solid tumor but very little is known about this event in non-solid tumors such as leukemias. Indeed, it has been demonstrated that in chronic lymphocytic leukemia (B-CLL), cells show a high OXPHOS activity and elevated ROS levels. Notably, expre

The objective of this thesis was to investigate how cell viability can be maintained in rested ischemic teleost white muscle (WM) during post-mortem (PM) storage.

Exercise prior to anaesthesia severely depleted the ATP generating potential of the WM (estimated by WM pH) from yellow-eye mullet (Aldrichetta forsteri) prior to PM storage, reducing the pre-rigor period. Fish anaesthetised in a rested state had a high ATP generating potential (intact ATP, PCr and glycogen WM stores) with ATP being able to be s

The current research sought to investigate post-transplant beta-cell viability and function by investigating the effects of low oxygen levels on MIN6 pancreatic beta-cells. MIN6 beta-cells were exposed to 1% oxygen (hypoxia) or 21% oxygen (normoxia) over a period of 72 hours. Viability was assessed by MTT assay and cell number was determined by haemocytometer c

Accurate replication of the genome during cell division is essential for maintaining genome integrity and suppressing diseases such as cancer. DNA replication forks can stall, collapse and/or break when they encounter obstacles present in DNA. This causes DNA replication stress, which is a major source of genome instability and mutations during carcinogenesis and cancer evolution. A number of studies have investigated how cells respond to replication stress by using various genotoxic agents such as radiation or therapeutic agents.

Abstract:

Leishmaniasis is a disease that is caused by obligate intramacrophage protozoa belonging to the genera Leishmania. The major Leishmania species responsible for the condition are L.major, L.infantum, L.chagasi, and L.donovani, including 20 other Leishmania species. The disease is endemic in 60 countries worldwide. This study aims to evaluate the antileishmanial activity of black seed extract of Nigella sativa collected from Kashmir. The extract was prepared by maceration along with the methanol. The antileishmanial activity was evaluated against Leishmania major using MTT (3-(4.5-dimeth

Abstract:

Numerous premature infants subjected to oxidant stress are afflicted with retinopathy of prematurity (ROP). Reactive oxygen species (ROS) and increased products of peroxidation with vasoconstrictor and cytotoxic properties ultimately lead to the degeneration of retinal microvessels. However, synthesis and activity of the vasodilator, nitric oxide (NO), are increased in the newborn. Furthermore, NO has been reported to protect cells, including endothelial cells, against injury associated with excess production of ROS. We thus postulated that NO plays a protective role in the development of oxyg

Abstract:

Fruits and vegetables are known to play an important role in human health due to the range of phytochemicals they contain. Twenty-one peach genotypes and 45 plum genotypes with different flesh and skin color were analyzed for their antioxidant content and antioxidant activity. Anthocyanin content, phenolic content and antioxidant activity were higher in red-flesh than in light-colored flesh peaches. Carotenoid content was higher in yellow-flesh peaches. Among the peaches, the antioxidant activity was well correlated with phenolic content. The anthocyanin content among the plums increased with
